Three-point perspective
2. A general rule to follow in this case is small objects look better if
the three vanishing points are well separated. The perspective angle should
not be acute. To emphasize the bigness of an object, sharp diagonal lines
are important. Here the closeness of the vanishing points strengthens the
bigness effect.
a. Be sure that the horizontal lines end at the eye level line, be
cause one cannot be higher or lower than the other.
Regardless of their
distance apart, they must be established on the same eye level.
In any
perspective drawing, it is a good idea to use the sketching method and
lightly sketch the object before finding the horizon line and vanishing
points.
b. In drawing any form, the proportions should be correct.
This is
especially true when drawing form in perspective. At the beginning of this
chapter, we introduced into our discussion the cube, the basis for all good
drawing. In order to solve many practical problems in art, you must become
acquainted with methods of measurement as they apply to this geometric
solid.
3. Before making measurements of any kind, establish the needed vanishing
points and station point.
Next, correctly sketch in the overall shape of
the object. If you do not, you may wind up making endless corrections, and
the drawing will never be quite right artistically. To divide a rectangle
or a square, draw a diagonal line from corner to corner as shown in Figure
3-2. The
